The Wizarding World is alive with excitement as the HBO Harry Potter series continues filming. Fans have been treated to a thrilling first glimpse of John Lithgow in full costume as the iconic Headmaster of Hogwarts, Albus Dumbledore. Mysterious set photos circulating online show Lithgow, with his characteristic long beard, on what appears to be a beach location, sparking immediate speculation about the scene's context.

This sighting aligns perfectly with the series' ongoing production, which began in summer 2025 at Leavesden Studios. While the show is committed to being a faithful adaptation of J.K. Rowling’s original seven books, this Dumbledore reveal comes alongside news that the series will also feature scenes not directly from the original source material. This approach aims to allow the showrunner, Francesca Gardiner, and the creative team to explore the rich storylines and characters in greater depth, offering fans new insights while honoring the core narrative. The commitment to a 10-year, seven-season plan, with each season covering one book, provides ample opportunity for such expanded storytelling.
